About the '=' Padding

Base64 encoding requires the input length (in bytes) to be divisible by 3. If it's not, padding is added: One '=' character is added when the input length modulo 3 equals 2. This ensures the encoded output is properly aligned.

Step 1: Map ASCII Characters to Binary

ASCII Character	Binary Value
i	01101001
s	01110011
o	01101111
l	01101100
a	01100001
t	01110100
e	01100101
d	01100100

Step 2: Group Bits into 6-bit Chunks

The binary string is grouped into 6-bit chunks for Base64 encoding:

011010 010111 001101 101111 011011 000110 000101 110100 011001 010110 0100

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011010	a
010111	X
001101	N
101111	v
011011	b
000110	G
000101	F
110100	0
011001	Z
010110	W
0100	Q

When combined, these characters form the encoded string: "aXNvbGF0ZWQ="
